PROBLEM TO BE SOLVED: To provide a bath water circulating device preventing dust from entering into an attachment when the attachment capable of extending a bath water jet nozzle to a desired position in a bathtub is attached to the bath water jet nozzle provided in a bathtub side wall and preventing the caught dust from escaping even when detaching the attachment. SOLUTION: This bath water circulation device has a bath water suction port for guiding hot water in a bathtub to the outside, the bath water jet nozzle introducing the bath water to the bathtub, an air suction passage taking air from the outside, communicating with the bath water jet nozzle and mixing it with the bath water, a circulation pump sucking the bath water from the bath water suction port, delivering it from the bath water jet nozzle into the bathtub and circulating the bath water between itself and the bathtub, and the attachment having a nozzle defining a connecting part detachably connected to the bath water jet nozzle as one end and delivering it to the other end via a hose guiding the jet flow jetted out from the bath water jet nozzle. This device is provided with a dust filter for collecting dust mixed in the bath water, between the connecting part and the bath water jet nozzle. COPYRIGHT: (C)2007,JPO&INPIT
